CHANGE-MAKER.

-- Specification of Letters Patent.

Patented July 1c, 1915.

Application filed May 5, 1916. Serial No. 95,580.

To all whom it may concern."

Be it known that we, MAX C. BRUHN and Gnonon F. MCGILL, citizens of theUnited States, residing at Chicago, in the county of Cook and State ofIllinois, haveinvented certain new and useful Improvements inChange-Makers, of which the following is a specification.

This invention relates to a holcler'and dispenser of coins for makingchange, and the principal objectof theinvention is to pro vide a new andimproved construction, combination and arrangement of 'partsforaccomplishing the desired result. I

In the drawings, Figure 1 is a frontelevation with parts broken away, ofa change maker constructed in accordance with the principles ofour-invention; Fig. 2 is a sectional view; Fig. 3 is a sectional viewtaken on line 38 of Fig. 2; Fig. 4: is a sectional view taken on line Hof Fig. 2; Fig. 5 is a plan view of a portion of the operatingmechanism; and Fig. 6 is a perspective of one of the operatingmechanisms.

In the present invention, the numeral 1 designates generally a casingwhich-may be made of'any suitable material such as metal or wood, and inthe present form the casing is provided with a removable front 2,

having a hinged top 3 which is held in place by a spring catch 4 at oneor both ends of the casing.

Supported by the casing are a plurality of coin-holding tubes ofdifierent sizes, each opened on one side and adapted to contain coins orchecks of difi'erent sizes. These tubes are rigidly supported by thecasing and are inclined from the vertical, as shown more clearly in Fig.2, with a rounded portion 6 adjacent the bottom of each tube bent at aslightly diflerent angle, more nearly upright than the remainder of thetube. Ihis rounded'portion 6 also conforms more nearly to the curvatureof the coin for whichthe particular tube is designed and intended.

At the bottoms of the tubes 5 is a plate 7 for supporting the stack ofcoins in each tube. The inclination of the tubes from the verticalposition takes some of the weight of the stack of coins from the bottomplate so that no matter how high the coins are plate 7, and consequentlyon the bottom coin, will not be excessive. This bottom plate 7 is formedbetween the sides of each tube with a notch 8 from the center of whichextends a curved slot 9. A shaft or pin 10 is secured to the bottomplate 7 and depends from the plate at approximately the center ofcurvature of the slot 9. Pivoted on the pin is an ejecting member 11pressed upwardly against or in the direction of the plate 7 by means ofa spring 12 which is held on the pin 10 by nuts 13 or other suitablefastening means operable also to adjust the tension of the spring. A

At the rear of each coin tube 5 is a slot 1 1 in the bottom plate 7.Through this slot extends one arm 15 of a key-lever 16- which is pivotedon a shaft 17 mounted below the coin tubes in brackets 18. The other arm19 of each key-lever extends through a suitable gaged to press the arm15 of the key-lever to the rear of the slot 14. I

Each projecting member 11, as shown more clearly in Fig. 5, is providedwith an irregular slot 23 which extends at an angle to the slot .14 inthe bottom plate 7 but crosses it, so that the extremity of the-arm 15of the key-lever 16 also extends through the slot 23 of the ejectingmember. Projecting upwardly from the ejecting member 11 through the slot9 of the bottom-plate 7 is an ejecting projection 2a which is cut awayat the rear, as designated by the numeral 2 5, and as viewed in Fig. 6,so that in the forward movement in the slot 9 the projection 24 willengage the rear of the lowerm'ost coin because of theyielding action ofspring 12 which tends to press the ejecting member 11 upwardly againstthe bottom plate 7. Also extending upwardly from the front of eachejecting member 11 and forming an integral part thereof is a project-ion26. the top of which'is in the plane or just above the plane of the topof the bottom plate 7. At the rear of this projection 26 is an inclinedportion 27 which extends below the .top of the bottom plate at alltimes. The normal position of this projection 26 is in the notch 8 atthe front of each coin tube, substantially in front of the slot 9. Theobject of the projection 26 is to engage the lower and outer edge of acoin positioning it in the tube by tipping the front of the coinoutwardly, thus insuring that it rests directly upon the top of plate 7so that the rear of the coin will be in position to be engaged by theejector 2% upon its forward movement. Without this projection 26 itmight happen that if there were only a few coins, or only a single coinin the tube it might have tipped downwardly at the forward side of thecoin and therefore the ejector in moving forwardly would fail to engagethe rear of the coin and hence would not eject it; but by providing apro ect on 26 at the front of each coin tube the coins are positivelypositioned and properly held upon the bottom plate for engagement by theejector 24.

I11 order to prevent the ejection of more than one coin from each tubeupon a single operation of the ejector, a detent plate 28 (see'Fig. a)is attached to the lid 3, which has projections 29 extending downwardlyto a point above the top of the bottom plate 7;, depending upon thethickness of the coin for which the tube directly opposite any one ofthe projections 29 is designed. 7 These projections 29 permit thedispensing of a single coin but prevent more than one coin from beingejected from. the tube at the same time.

Arranged at the front of the tubes 5 and within the casing 1 just belowthe cover 3 is an inclined hute 30 which extends through an opening atthe end of the easing fordischarging the coins into another chute 3 1attachable to the outside of the easing. This chute 31discharges thecoins into a receptacle 32 preferably in the form of a shallow-dish,from which they-are easily removable. This receptacle 82 may be maderemovable-by providing it with a bracket 33 into which a tongue 84secured to the chute 31 extends. At thebottom of the chute 81 orsecured, to the receptacle 32 is a bridge 35 extending substantially thewidth of the chute 31 to engage and prevent coins from rolling down thechute thuscausing them to slide into the receptacle so they will notjump over or out of it.

The arrangement of the chute 31 and receptacle 32 is optional, dependingupon the place in which the change maker is used. Thespecificconstruction above'described is particularly adapted for use inconnection .all or any of the key-levers may be depressed at the sametime. Upon the return of the ejecting member not only will the ejector24 pass vertically under the stack of coins without disturbing them,because of the pressure spring 12, but also all of the coins, andparticularly the lowermostcoin of each chute will be pro erl 'posititnedby the projection 26 of the ejecting member so that the lowermost coinwillbe positively placed and held in position for engagement by the eector upon its next fprward movement. If the coins become clogged in anyof the tubes 5, in the chute 3O, or if it is desired to insert or removecoins from the tubes 5 it is necessaryenly to raisethe cover 3 bydisengaging the latch 4t and to manipulate the coins as desired. i Weclaim: I I r v v 1.
